The HV2809 serves as a sixteen-pole, double throw (16PDT), high voltage switch array. Using Supertex's proprietary HVCMOS technology, the IC efficiently controls analog signals with low power CMOS logic and high voltage bilateral DMOS switches. It features a very low quiescent current of 10µA for low power dissipation and a bandwidth frequency of up to 50MHz. The HV2809 also has an enable logic control, which allows it to be configured for 2:1 or 4:1 ultrasound probe select.

"Using the HV2809 to control medical ultrasound probes offers a number of advantages over electromechanical relays," states Jimes Lei, Director of Application Engineering for Supertex. "As technology moves forward and medical ultrasound systems become more compact, replacing the mechanical relays with the HV2809s will reduce board area, component height, and system weight."

The HV2809 is available in an 8x8x1mm 56-lead QFN package (HV2809K6-G). The part is RoHS compliant. Samples are available from stock. Lead-time for production quantities is 4-6 weeks ARO. Pricing is US$14.51 each for the HV2809K6-G in 1K quantities.
